3 Claims. (crew- 57) ihis invention relates to a mu'lti-valved pressure fluid manifold andv more-specifically to a manifold of this type that is particularly adapted for the control of fluidunder pressure to a pressure fluid jet head of a stoker. i

In many types of Stoker's, in fact all current types of locomotive'stekers, coal is projected over the firehed by steam blasts issuing from a pressure flu id jet head. The jetheadis divided 1ongitu'dinally into 'aplurality of s i'de-by-side' dis-- posed chambers from each of which steam issues through jet orifices, of which'there may be seve'ral to each chamber. 'A' plurality of pipes, one

ment between a pressure fiuid manifold and a pressure fluidjeth'ead of a stoker- Other objects and advantages of the invention residing in the construction of the parts thereof and the combination and arrangement of various 7 elements will become apparent from the following leading to eachchamber, are connected by a manifold disposed aboveand toone side'of the jet head Within easy reach of the operator, with a main steamlineleading from -a-*suitable source of supply. The jets of "steam issuing from the orifices of the several chambers are directed-to ward predeterminedzareas of the'firebed, and in tion;

order to provide for adequate control of the intensity of these blasts, and thus for theeifective control of fuel distribution, a valve is provided in each of the pipes subjacent the manifold, as

shown in U. S. Patent No .-1, 904,520, or a valve;

controlling the flow of steam to each pipe is pro- Patent No. 2,086,692.

In order to avoid confusion as to which valve controls which steam chambenthevalvesare genn erally arranged in the same order from left to right as the order of the steam chambers of the jet headthat they are to control, i. e., the, valve farthest to the left controls the flow of steam'to the steam chamber farthest'to the left, the secondvalve from the left controls the flow of steam to the second steam chamber, on in order.

from the left, and; so

reviously, this has reouir'ed fcrossing'foffthe as shown in" U. S.

steam pipes between themanifold and the jet:

head, or it has required the provision of a complicated jet head structure, which, while it eliminated crossingof the pipes, necessitated disalignment of the pipes in transverse vertical planes.

I .With reference now to Figs. and v2 of. the drawings, a stoker discharge conduit is shown at Iii and it communicates with: a firing opening H 5 in the backwall [2 of Ta locomotlve firebox' l3.

. The conduit Llil delivers fuel onto a distributing table l4 extending through the firing opening H and from which table the fuel isprolected into the firebox to the various parts of the firebe d by blasts of ,fluid under pressure, preferably steam,

The present invention eliminates the various disadvantages of past practice and one of its objects is. to provide a new and novel pressure fluid manifold, so constructed that the fluid outlets are ininverse order from left to right with respect to-theorder' of the valves controlling the emission of fluid from said outlets.

Anotherobject of the-invention is to provide a simplified and advantageous piping arrangeissuing from the pressurefiuid jethead; I5. e The jet head 15 is provided with a plurality of separated chambers, such as 1 605 162), Ito, Mid

.and [6e arranged to receive fluid under pressure from a suitable source of supply through the pipes Ila, .I'lb, llc, lid, and He respectively. The blasts of fluid under pressurefor projecting fuel from the table 14 issue from the jet apertures 21 of the jet head l5,'a plurality of such jet apertures; preferably, communicating with each of the chambers did, b, 0,112 and e.

.mThe'streams of pressure fluid issuing from the jet aperturesof theseveral chambers are, directed the valve second from the right.

toward predetermined areas of the firebed, and in order to provide for adequate control of the intensity of these blasts for effecting proper control of fuel distribution, delivery of pressure fluid to the pipes Ila, lib, l'lc, lid and He is con-. trolled by valves, designated, respectively, as I8a, i8b, I80, IM and lfie, each of which is manually controlledand carried by the manifold M.

It will be observed, as the description proceeds, that the valves ISa, I82), I80, [8d "and I'8e'a're rranged in the same sequence from left to right as the chambers I6a, IBb, IBc, Mid and IBe'"to which they respectively control the flow'of pressure fluid. This is highly desirable from the standpoint of the operator, si'nceifhe {desires to 3 vary the intensity of the "'blas't issuing from "the extreme right hand chamber lee for the purpose of increasing or decreasingthe"amount-of coal projected to that area of the firebed affected by the blast issuing from chamber lEe, he'rrla'nipulates the 'eXtreme-righth-and valve--I-8e. Similarly, if he desiresto vary-the intensity of the blast issuing from =-chamber hid, the chamber second from the right,"he-mani-pulatesfvalve IBd,

Thedesirability of arrangingthe'valves in the same sequence as the-jet-head chambers has been recognized in the past, as shown in Pickard Patent 1994520 and Roesch Patent 2,160;563. In order to-accomplish this, Roeschcrossed' thepipes leading'fro-m the manifold to the jet-head and Pickard provided a specially constructed jet head that still necessitated-the crossing of some of the pipes. -My inventionincorporates-a novel manifold that eliminates crossing'of the pipes leading from the manifold to the jet heaipermitting them to be arranged' in the same transverse vertical plane whereby they; can-be disposed closely adjacent the locomotive backhead I2 and are easily and convenientlyinstalled and readily accessible for removal when necessary,

The; construction of the novel manifold is shown in Figs. 3 to 8, inclusive, and will nowbe described in detail. The manifold M'is generally oblong in shape-and includes a front Wall 22, rear Wall 23, top'wall'24, bottoinwall .25 and end Walls 25 and 21. A flange 28 is prdv'iddat each of the four"'corne'rs of "the manifold rear Wall 23, through which flanges the manifold is secu'redtothe back wall I2 by'suitable' means such as the bolts 29, as best shown inFig'fZ.

A partition wall 30, extending transversely between the end Walls 26 and 21 trtne'mamrom, forms in theupp'er portion of the'manifo1d a main chamber'3 l, A main lead32 conducts fluid under pressure from a suiteme'soure ofsnpply, such as the steam boiler of the ieeemenve, to the main chamber 3 I through "an 'intake ope'rring 33 in the top wall- 24 f theirlanifoldlvl. DA manually controlled 'valvernot shown) "is-provided in the main lead'32 between the mani'fold Mand the source of 'fiuid'under pressure for cb'ntrolling the fluid pressure in the'iriainpha'nibr 31.

The lower portion of the manifold'M-is divided by partitions into five separate and distinct passages, designated as [9a, "I9b,':l9c, I911 a'nd I92, there being the same number of passages as there are pipes leading from the manifold M to the jet head I andas there'are oharr'ibers in'the jet head l5.

and I96 communicate at 'oneend-w-i'th' the 'main the passage of pressure fluidfromcthe niain The pas'sages ISaQ-ISbQIQC, 19d

He and thence to the jet head chambers IBa, I61), I60, led and IBe, respectively. Communication between the main chamber 3| and the passages I911, I91), I90, I9d and I9e is effected by means of inlet ports 20a, 29b, 20c, 20d and 202, respectively, formed in the partition wall 30 and spaced in a row extending transversely between the ends of the manifold. Communication between the passag'es 19a, I9b, I90, HWan'dWS'e and the plpeslla, Ilb, II'c, Nd and He, respectively, is effected by means of outlet "ports a, 35b, 35c, 35d and 35e, respectively, formed in the bottom wall 25 of the manifold and spaced in a row extending transversely betwen-the-iendsoffthe manifold, the axes of the 'outietpo'rtsbeingdisposed in the same transverse verticalplane.

It willbe observed that the passages I8 are 7 so arranged in the manifold that their inlet ports '23 are in inverse order of their outlet ports 35. ln-ether'words, the inlet-ports 200i the passages lQ'are arranged iromfileft to rightin the order I c, b, '0, stand e, 'while the-outlet ports -35 are arranged frcm lefttoright-in the-order e, d, c, b and a. 1

As 'was previously mentioned, the manifold M carries valves I8 for controlling-the-flow ofpressure fluid to the-jet head chambers I 6, in consequenceof which the distribution of fuel to desired portions of the --ii rebed can be effectively controlled. The valves I 8a, I8b, I80, I 8d and I8e control the ergtent-of the openings of'the inlet ports 20c, ZOd and 20c, respectively,- and there-fere-tl'i efvolume of pressure fluid delivered totheipassages-laa, I9b, I'9c, I'.9d,,and'|9e,"respectively;

-As bestshown in Figs. 3, 4-'and 5, passagei5c extends vertically through the central'front portionpf the manifold, both its' inletport 200- and outlet port 35c being-disposed centrally between the ends of themanifold. "The other passages, I-Ba, lab, 19d and "I9'e, as bestshown'in Figs-4 land- 5, cross over behind-passage cfrom one side to the other side thereof, passages IBa and'I'9b having tlleil'jlnlet ports 20a, and-20b at the left of inlet port iflc and their outlet ports 35a'and '35bat the right ofoutletport"35c, and passages at the right-of inlet port iflcand their outlet rtsfsedena ssear'the leftof outletTport' 35d.

In-"Fig. 3'tlle'valve' IBc is'shovvnin detail as appliedto"inlefport,"20c. The details of valves Illa, [8b, I811 and Illcare'not "shown since the construction thereof is identical with thatof valve I'8c. Referring 'toFigj'3, valve 18c comprises 'a stem 40" threaded into a bonnet-4 I the stem" having a"va1v ";nemper 42 at its' "inner end and thevalve 'h'andle43 'atits outenend. nflval've seat 44 is threaded into the body of the manifold 60 the inlet-port fllc and isarranged -to receive the-valve s ems-a 32, "fIhe setting of valve I 'deter'miriesthej amount ofprcss'ure'fluid admitted to the passage19cnearineman:chamber 3-I I' In operatiom as'sunfing for purpos'e of illustration-ft hat the op'e'rator desires td fire theextreme left side of the firebed heavier, he opens the'valve I8a -at the extreme- 1ers oftlie manifoldw'ider. Ope'nin'g cf the valve lsa permits pressure iluid'to pass irom 'the*main' chamber-aii I to; passage I 9a "through inlet-"portllla' tflig. '7). Passage IQa,

'as' shown in Fig; 4-'leads to'the extreme right-side of the'manifold ancr communicates with pipe I-la through outletlport a (Fig: 5) 'Thepressure "fl'uid 'is-thus conduoted'th'roaghthe manifold by "passage :I9a from-the inlet port -at 'theleft to the outlet port at the right, thence passes through pipe Ha to the jet head chamber Ilia, from which chamber the pressure fluid issues through the jet apertures 2i projecting the fuel to the extreme left side of the firebed.

If it is desired to vary the intensity of the blast issuin from the extreme right hand chamber Hie, the operator manipulates the extreme right hand valve I8e (Fig. 2), whereby the flow of pressure fluid from the main chamber 3! to passage We is controlled. The pressure fluid passes through port 20c into passage l9e (Fig. 5). Passage 19c, as shown in Fig. 8 leads to the extreme left side of the manifold and communicates with pipe He through outlet port 35c (Fig. 5). The pressure fluid is thus conducted through the manifold by passage I96 from the inlet port at the right to the outlet port at the left, thence passes through pip We to the jet head chamber ice, from which chamber the pressure fluid issues through the jet apertures 2 l, controlling distribution of fuel to the extreme right side of the firebed.

In similar manner, the path of the pressure fluid to chamber 161) can be traced from main chamber 3| through inlet port 28b (Fig. 6) to passage ISb, then through passage l9?) (Fig. 4) to outlet port 35b, thence through pipe i'lb (Fig. 5) to chamber lBb. Pressure fluid to chamber [6d passes from main chamber 3! through inlet port d to passage [9d (Fig. 5), then through passage [9d (Fig. 8) to outlet port d, thence through pip I'Id (Fig. 5) to chamber ltd.

It is apparent from the above description that my novel pressure fluid manifold provides for arrangement of the valves in the same order as the jet head chambers to which they control the passage of pressure fluid. At the same time, the piping from the manifold to the jet head is maintained closely against th firebox backwall. A symmetrical piping arrangement is provided, obviating crossing of pipes and making them conveniently accessible and easily installed or replaced.

While my invention has been shown and described as applied to th firebox of a locomotive, it is apparent that it is equally applicable to other typesof firebo-xes.
